MAX3086CSD+

Overview

The MAX3086CSD+ is a +5V full-duplex RS-422/RS-485 transceiver in a 14-pin SO package. It supports data rates up to 10Mbps with no slew-rate limiting. The device features fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It operates within a supply voltage range of 4.75V to 5.25V and draws 375µA typical quiescent current. The component provides 1/8-unit-load receiver input impedance, allowing up to 256 transceivers on the bus.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output during idle or fault conditions
• High-speed transmission capability up to 10Mbps without slew-rate limitations
• Low-power shutdown mode for energy conservation

Applications

• RS-422/RS-485 communications
• Industrial-control local area networks
• Level translators

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) against the datasheet specifications. Confirm the '+T' or standard packaging format matches the required reel or tube quantity for the manufacturing process. Ensure the 14-SOIC footprint aligns with the PCB layout constraints.

Selection Notes

Select this component for applications requiring high-speed full-duplex communication at 10Mbps. It is suitable where fail-safe operation is critical to prevent bus contention errors. Consider the 1/8-unit-load specification if designing networks with a high node count exceeding standard 32-node limits.

Part Context

This part belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485 and RS-422 standards. Unlike lower-speed variants in the series, the MAX3086 specifically omits slew-rate limiting to maximize throughput. It shares pin compatibility with industry-standard devices like the 75180.

Replacement Considerations

The MAX3086 is pin-compatible with the 75180. Other family members such as the MAX3080 or MAX3083 offer similar functionality but operate at reduced maximum data rates of 115kbps or 500kbps respectively.
